## Detailed Description

RecoveryPointAdapterImpl virtual base class for implementing external storage of subscription recovery points and recovery from storage.

## Member Function Documentation

## ◆ next()

virtual bool AMPS::RecoveryPointAdapterImpl::next | ( | RecoveryPoint & | current_ | ) |
| pure virtual

Recovery is done by iteration over elements in storage.

This function modifies the passed in argument to be the next stored RecoveryPoint or an empty RecoveryPoint to indicate completion.

Parameters

  current_ | The RecoveryPoint to set as the next recovery item.

Implemented in AMPS::SOWRecoveryPointAdapter, and AMPS::ConflatingRecoveryPointAdapter.

## ◆ purge()

virtual void AMPS::RecoveryPointAdapterImpl::purge | ( | const Field & | subId_ | ) |
| pure virtual

Remove the specified subId_ from the storage.

Parameters

  subId_ | The sub id to remove

Implemented in AMPS::SOWRecoveryPointAdapter, and AMPS::ConflatingRecoveryPointAdapter.

## ◆ update()

virtual void AMPS::RecoveryPointAdapterImpl::update | ( | RecoveryPoint & | recoveryPoint_ | ) |
| pure virtual

Update the storage information with the given recovery point.

Parameters

  recoveryPoint_ | The new/updated RecoveryPoint to save.

Implemented in AMPS::SOWRecoveryPointAdapter, and AMPS::ConflatingRecoveryPointAdapter.
